Application filed February 9, 1920.

T 0 (IN whom it may concern:

Be it known that we, PHILLIP H. HOHMANN and EZRA E. TNNIS, citizens of the United States, residing at Laurel. in the county of Yellowstone and State of Montana, respectively, have invented new and useful Improvements in Stoves, of which the following is a specification.

This invention comprehends the provision of a stove designed to be carried by an auto mobile or the'like, wherein the exhaust gases are utilized as the heating agent.

In carrying out the invention, use is made of a receptacle wherein the sides and back include spaced walls defining chambers through which the exhaust passes, the chambers having positioned therein bafiies of different construction that cause the exhaust gases to pursue a zig-zag course in passing from one chamber to the other, so as to effectively heat the interior of the stove, before the gases are exhausted to the atmosphere.

Another important object of the invention, resides in the novel manner of closing the containers removably positioned within the stove and providing a valve controlled vent for the containers.

The nature and advantages of the invention will be better understood when the following detail description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this specification, like numerals of reference indicate similar parts in the several views and wherein:

Figure 1 is a view in elevation of the stove forming the subject matter of the invention.

Figure 2 is a front view showing the door opened.

Figure 3 is a vertical sectional view taken on the line 33 of Figure 1.

Figure 4 is a horizontal sectional view taken through the stove.

Figure 5 is a sectional view taken through one end of the stove.

F igure 6 is a sectional view taken through the back of the stove.

Figure 7 is a perspective view with the top removed.

The stove forming the subject matter of this invention, is preferably in the nature of a receptacle indicated generally at 10, and

ed for use in connection with automobiles or' the like, and may be positioned at any convenient or desirable location on the car and connected with the exhaust by means of the pipe 18, the latter leading from the exhaust pipe into one of the chambers 17 The bottom 12 is formed with depressions20 for the reception of the cooking vessels or the like indicated at 21. Arranged within the stove, is a top or cover 23 for each of the cooking vessels, the tops being associated with coiled springs 24:, which function to effectively maintain the closure of the tops in position upon the vessels as shown. Each closure or top 23 is associated with the pipe 25 which communicates with the vent pipe 27 to allow for the escape of steam from the vessels as will be readily understood. The chambers 17 are separated by the partition 28 which extends across the receptacle in the space between the bottoms thereof as illustrated. this partition forming part of a curved bafiie plate 29 which is arranged in the space be tween the rear walls and curved upwardly and in the direction of one end of the receptacle. This battle is continued as at 30 and extended across one end of the receptacle terminating short of or in spaced relation to the front wall of the receptacle. An -addi tional baffle plate 31 is arranged in the space between the rear walls of the receptacle and extended longitudinally thereof from the baffle plate 29 to the opposite end of the receptacle, this baffle being continued as at 32, the portion 32 being curved upwardly and forwardly in the space between the said end of the receptacle terminating in spaced relation to the front wall of the receptacle as shown. It will be noted that the exhaust is conveyed into one of the chambers 17 through the pipe 18, the exhaust filling the space between the bottoms of the receptacle in this particular chamber and also the space between the ends and rear walls of the receptacle. The exhaust circulates about this chamber 17 as indicated by the arrows in Figure .7, striking the baflie plates 29 and 30 which directs the exhaust to pursue the course indicated by the arrows over the batfle plate 30 and thence rearwardly to fill the space between the rear walls of the receptacle about the baffle plate 31. The baffle plate 31 directs the exhaust toward: one end of the receptacle as indicated by the arrows, filling the space at this end of the receptacle, where in the exhaust is directed by the baffle plate 3.2 to pass betweenthe forward end of this baflleplate and the adjacent wall of the receptable, under the bafile plate 32 and thence into the chamber 17 at the right side of the partition 28 as illustrated in Figure 7, filling the space between the bottoms of the receptacle in this particular compartment, and finally escaping to the atmosphere through the pipe 33. While in use, the top 15 and the door 14 are eliectively closed and maintained in closed position in any suitable manner. When it is desired to remove the vessels 21, the latter are slightly elevated against thetension of the springs 24 and removed through theopen frontof the stove.

l/Vhile it is believed that from the foregoing description,the nature and advantages of the invention wilhbe readily understood,

we desire to have it understood that we do not limit ourselves in the construction herein shown and described, and that such changes may be resorted to when desired as fall with in the scope of what is claimed.

.Having thus described our invention what we claim as new is:

A stove for automobiles, comprising a re ceptacle providedwith spaced walls, a door controlling access to the receptacle, a pipe connected to the exhaust pipe of the automobile and extending'into said receptacle between said spaced walls, baflle plates disposed between the spaced walls of said receptacle, vessels removably positioned in the receptacle, a cover for each of said vessels, a horizontal vent pipe extending into said receptacle above said covers, vertical pipes extending from said covers and communicating with said vent pipe, a cover hingedly secured to said receptacle, coil springs secured to the bottom of said cover and adapt ed to engage said vent pipe, and a pipe extending into said receptacle between said spaced walls and communicating with the atmosphere.

In testimony whereof we afiix our signatures.
